# Transaction Flow * Apps request an MSB validator to get a transaction for a smart contract operation validated. * The MSB validator checks the request - and if successful - signs & appends the transaction on the decentralized MSB ledger. * The app waits for the transaction to get finalized by the MSB consensus and performs the smart contract operation. * The result of the operation is signed & appended on the app's decentralized ledger if the consensus agrees on the outcome. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
